Question

A particle is moving in x-y plane such that its
position co-ordinates are varying w.r.t time as
x = 5sin121 nt and y = 121cos5t (where x and
y are in meter and t is in second). The speed of
the particle at t= 1 s is​

Answer 1

Answer:

60θ = 10π θ = π /6 V⃗A = - v0 cos 30oî - v0 sin 30oĵ = - v0/2[√(3)î + ĵ] V⃗B = V⃗A = - -V_o/2[√(3)î + ĵ] a⃗B = -V_o/2[√(3)î + ĵ] ...

Top answer

60θ = 10π θ = π /6 V⃗A = - v0 cos 30oî - v0 sin 30oĵ = - v0/2[√(3)î + ĵ] V⃗B = V⃗A = - -V_o/2[√(3)î + ĵ] a⃗B = -V_o/2[√(3)î + ĵ] ...
